Abstract: A method of selectively depositing tungsten upon a silicon semiconductor substrate (1), on which a masking film (2) of PSG or SiO₂ is coated and patterned to provide an opening (3) for forming an electrode or wiring therein. On a portion of the substrate in the opening (3), approximately 2000 Angstroms thickness of tungsten (4) is deposited by a CVD method, in which tungsten hexafluoride gas and hydrogen gas are used and the substrate is heated. As a result of this processing, some tungsten nucleii are deposited on the surface of the masking film (2). Before the nucleii form a film, the deposition processing is discontinued and a hydrogen gas is fed in to produce hydrofluoric acid, which etches the surface of the masking film (2), thus to remove the tungsten nucleii thereon. The above-described processings, i.e. deposition and removal of tungsten, are repeated several times until the heights of the deposited tungsten (4+4ʹ+4ʺ..) and the masking film (2) become practically equal, forming a flat surface.

Abstract: A method and apparatus for simulating memory devices in a logic simulation machine (10,12,16,18). Both include a finite state machine (FSM) having input/output (I/0) sources, instruction storage resources, a real memory resource, and instruction execution resources. A plurality of memory device ports to be simulated are defined and associated with corresponding respective subsets of the I/O resources of the FSM. Permutated sets of simulated memory array access signals, such as data, address, and control, are bound to selectable ones of the simulated memory ports and stored in the FSM, with the parameters of the memory operation established by the simulated signals. Stored sets of access instructions, representative of memory access operations, are augmented by the simulated signals and executed by the FSM against the real memory resource. All array instructions representing the same memory array share the same address space in the real memory resource.

Abstract: Two interacting stacks (26,28) of peripheral overlapping shredding members of disk form are mounted on substantially parallel shafts (30,32) and positioned transversely to the direction of waste material passing through a comminutor casing (10ʹ). The casing opens upstream and downstream side for introducing liquid borne waste to the chamber and for discharging the comminuted waste therefrom after shredding, respectively. The casing is closed off by a pair of imperforate side rails (20ʹ), each side rail (20ʹ) is slotted to form a series of inwardly projecting planar fingers (74) having front edges of circular arc form facing the periphery of the rotating cutting element disks (52,54) and having a radius larger than the radius of the disks (52, 54) and being spaced slightly therefrom. The array of fingers (74) extend over the complete height of the stack (26,28) shredding members. This facilitates greater flow of the liquid through the comminution chamber via slots between the fingers (74) carrying fine solids to enhance comminution.

Abstract: A filter apparatus comprises a plurality of ceramic porous filter elements (l) each having parallel passages separated by filtering walls, with the passages closed at either the inlet side (4) or the outlet side (6) to form inlet and outlet passages respectively. The elements are in individual casings (l5) piled one above the other with the filter elements (l) being spaced apart from each other. Raw liquid to be filtered is supplied to the inlet sides (4) of the filter elements via supply chambers (36) located between the filter elements. Filtrate discharge chambers (37) are located between the filter elements for receiving filtrate which has passed through the filter elements. With this arrangement, raw liquid passages and filtrate passages are completely separated, so that no mixture of the raw liquid and the filtrate occurs, and therefore filtering can be effected with high efficiency and high reliability. The apparatus can be light in weight.

Abstract: This invention relates to gradation display by pulse width control method (PWM method) in every pixel in a capacitive display apparatus such as liquid crystal display apparatus. The driving voltage applied to the electrodes is variable slowly, and the number of grada­tions of gradation display by PWM method is increased. Since the capacitive display apparatus is used, as going away from the drive circuit of the electrode for each electrode, the driving pulse is more influenced by the capacity, and its persisting duration is extended. As a result, even in identical gradation data, uneven colors may occur. In this invention, the pulse width applied to the electrodes is gradually decreased as scanning of the electrodes is promoted. Therefore, the brightness of the capacitive display apparatus may be made uniform over the entire screen surface.
